Aaron Plessinger is now a well-established fan favourite at Supercross venues across the United States. His trademark cowboy hat make him one of the most easy to recognise riders during any AMA Supercross Championship weekend.

Aaron kickstarted his professional riding career with the Yamalube Star Racing Yamaha team in 2015. The rider from Hamilton, Ohio bagged an impressive podium finish in Anaheim during his AMA Supercross Championship debut season. Things got even better for Aaron in the 2015 AMA National Motocross Championship when he took his first-ever overall win in the professional ranks at that season’s final stop. A move from West to East saw Aaron finish the 2017 AMA Supercross Championship as runner-up in the 250SX East division.

2018 turned out to be the most memorable year of Aaron’s career so far with a pair of championship victories to celebrate. First he took the 250SX West title, thanks in no small part to a total of four victories claimed along the way. In the summer the Ohioan was crowned the 250 class champion of the 2018 AMA National Motocross Championship after claiming six wins during the season.

Aaron was promoted to the 450 class in 2019 and when injury-free he’s shown he has the speed to hang with the very best. Since 2022 he has been part of Red Bull KTM Factory Racing and enjoyed his best 450 motocross season to date with third place in the final standings of the 2023 AMA National Motocross Championship.

In 2024, he showed his talent, being a top three guy in 'The Cowboy' has been in spectacular form during 2024, holding the red plate for multiple rounds after picking up his first-career 450SX victory in San Diego, and then going on to claim additional podium finishes at the Anaheim 2 Triple Crown and in Arlington. He will unfortunately miss the final four rounds of Supercross with a fractured elbow, but is expecting to be READY TO RACE when the gates drop on the AMA Pro Motocross Championship in Pala, California, on May 25th.

For 2025, Aaron is back in orange for his fourth-straight year onboard the KTM 450 SX-F, continuing in the AMA Supercross Championship and Pro Motocross Championship as well as the three-race SMX Finals series.

"I'm really excited to be staying with Red Bull KTM through 2025. It is an awesome team and I think we're going to do some big things together in the future – even bigger and better than what we've achieved so far. I couldn't be more stoked to be staying within this family and building upon where we're at, the level that we have been able to reach this season. For this year we made some major changes in the pre-season and really haven't changed the bike at all since, which has really, really worked out in our favor. I've won my first Supercross Main Event, have gotten three podiums in total, and something's clicked for us this year. This is the most enjoyment I've had in my entire 450 career and I'm just enjoying the ride, which is rare, and I'm very fortunate. I'm stoked to be back for 2025, so hope we keep progressing and I will be doing my best to perform to the level that we aim to once I am able to line up again outdoors. I'll keep riding my heart out when I'm back from injury and am really blessed to be staying with the crew."
